I just picked up a used 2018 Goldwing. It had been sitting for ~ 8 months. When driving home the TPMS sensor was lit on the dashboard blinking 29 - 32 lbs. Only the rear wheel was displaying as there should be a front and rear tire pressure, correct? After about 1/2 hour it went off and the rear tire pressure showed 42, (front blank) which is recommended. I stopped for a few minutes and on start-up the same the same thing happened, and it went off after ~ 15 minutes. Will this fix itself, since it had been sitting for an extended period of time?
